TOOL FOR OJPERATING UPON INSOLES USED IN BOOTS AND SHOES.

Application filed October 19, 1921.

T 0 all whom it may concern:

Be it known that I, *JAooB R. NAUGLE, a citizen of the United States, residing at Carlisle, in the county of: Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Tools for Operating Upon Insoles Used in Boots and Shoes, of which the following is a specification.

This invention relates to tools for operating upon insoles used in boots and shoes.

In making a double lipped insole in which inner and outer lips are cut, turned up and secured together to form a compound lip, diiliculty has been encountered in turning up the inner or channel lip so that it can readily be secured to the outer lip and similar trouble has also been encountered in turning up the outer lip and in both cases, this trouble is particularly present about curved portions of the insole, that is the toe portion thereof.

One object of the present invention is to produce a tool for operating upon insoles by which the lips may be treated so as to enable them to be readily turned up in the desired position with relation to the body of the insole.

Other features of the invention consist of certain novel constructions, arrangements and combinations of parts, the advantages of which will be obvious to those skilled in the art from the following description.

In the drawing Figure 1 is an elevation of two of the tools showing the same as used in slitting the outer lip of an insole,

Figure 2 is a similar view looking from the opposite direction without the insole,

Figure 3 is a section looking downwardly on the line 33 of Figure 1,

Figure 4t is a detailed perspective view of one of the tools showing the lower portion thereof,

Figures 5 and 6 are sectional views taken through the tools similar to that disclosed in Figure 3 showing the same spaced from each other at different distances,

Figure 7 is a similar View showing the arrangement of a knife for cutting or slitting the inner lip of the insole,

Figure 8 is a section on the line 8-8 looking in the direction of the arrow, and

Figure 9 is a detailed perspective view ofthe insole slitting inner lip tool.

Serial No. 508,724.

Referring to the drawing in detail it will be seen that the slitting tools for the outer insole lip are used preferably in pairs and each consists of a shank 1 having the olfset portion 2 upon which is situated the main cutting blade 3 and the angularly extending portion l. This portion 4; preferably extends froin the main cutting blade 3 at an angle of about one hundred and twenty degrees for the purpose of slitting the outer lip as will be noted from an inspection of the drawing. These cutting blades 3 may be spaced from each other at any desired distances such as is indicated in Figures 5 and 6 but should always lie in substantially the same plane, whereas the angular extensions l converge toward each other at their ends and in Figure 5 meet.

The tool for slitting the inner lip of the insole consists of the shank 5 having the offset portion 6 on which is formed the cutting blade 7. This tool is associated with the tools 1 as is shown to advantage in Figure 7 or so that its plane is at right angles to the planes of the main blades 3 and so as one end thereof will be situated in close proximity to the converging ends of the auxiliary blades or angular extensions 1-. It should be noted that the slits formed by the tools 1 resemble a W in its upright posi tion or in its inverted position.

Having thus described my invention what I claim as new is A tool for operating upon insoles including in combination a pair of main blades, a pair of angularly extending blades associated with the main blades for slitting the outer lip of an insole, one angularly extending blade formed on each main blade, said main blades being situated in the same plane with each other and said angularly extending blades being situated so as to converge toward cach other, and a third blade for slitting the inner lip of the insole situated so as to have its edge adjacent the converging ends of the angularly extending blades.

In testimony whereof I ail-ix my signature in presence of two witnesses.
